Hi,
I have the same pb with SFR (vodafone france).
My first analyze is in the trackback. (

I think the problem is with services book and authorization to reach other networks from BB net.
EDIT : in fact, the real question could be : "Has anyone manged to get TomTom Plus Services working on an BlackBerry 8800 using "... any carrier
